I like SH4 alot and I also like fishing alot. Would be nice if I can do both at the same time

I know it sounds hilarious and totally 'unrealistic' but its FUN. Alot of time when i go to the DG view and look at the sea i have this urge to cast a fishing line.
while camping/patrolling it would be a real blast if I could also do some deep sea fishing to help with crew morale by providing fresh fish for meals
This can even make patrol with no TC possible.
ideas:
-Can purchase fishing gear upgrade with the pile of renown.
-Can boost crew morale via different type of catch?
-Can spot fish school with passive sonar.
-Can go back to wreck sites created by me or other kaleun and get extra fish catch? (fish love to congregate around ship wrecks).
Just a thought...
